It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0035] like Figures 1 to 8 As shown, an embodiment of the present invention provides a non-stop material discharge device, comprising a frame 100, a double-gas-inflating-shaft rotating component 200 and a material receiving component 300. The double-gas-inflating-shaft rotating component 200 can place at least two groups of coils (film materials) and can switch each coil to a loading position. The material receiving component 300 is used to dock the end and the starting end of two groups of coils (a first group of coils 291 and a second group of coils 291). The double-gas-inflating-shaft rotating component 200 includes a turntable 210 and a first rotating drive assembly 230 for driving the turntable 210 to rotate, the turntable 210 is rotatably connected to the frame 100, the first rotating drive assembly 230 is connected to the frame 100 and the turntable 210, and the turntable 210 is provided with a first shaft 201 for mounting the first group of coils 291 and a second shaft 202 for mounting the second group of coils 291; the first shaft 201 and the second shaft 202 can be gas-inflating shafts. When the first group of coils 291 are unloading, the second group of coils 291 can be used as spare coils to be received. When the first group of coils 291 are used up, the second group of coils 291 are connected to the end of the first group of coils 291 and then driven by the turntable 210 to rotate 180 degrees to switch to the loading position, and new coils are loaded at the position of the first group of coils 291, so as to realize continuous loading without stopping the machine in this cycle. The receiving component 300 is fixed to the frame 100 and is arranged adjacent to the double air shaft rotating component 200; the receiving component 300 includes a receiving frame 310, a docking component for fixing the starting end of the second group of coils 292 and for docking the end of the first group of coils 291 with the starting end of the second group of coils 292; the docking component is arranged on the receiving frame 310, which can realize continuous loading without stopping the machine, which is conducive to improving production efficiency and reducing production costs.

The coil being loaded is directly connected to the material receiving guide roller 320. When the spare coil to be connected is pulled to the material receiving component 300 for standby, the spare coil to be connected is close to the material receiving guide roller 320 and is separated from the material receiving guide roller 320 by the coil being loaded. When the end of the coil being loaded (the first group of coils 291) leaves the material receiving guide roller 320 to the setting position of the material receiving component 300, the docking component is actuated to dock the starting end of the spare coil to be connected (the second group of coils 292) with the end of the first group of coils 291. The first shaft 201 and the second shaft 202 are symmetrically arranged on the left and right sides of the center (center of the circle) of the turntable 210. In this embodiment, as Figure 1 As shown, the state can be switched by rotating the turntable 210 180 degrees.

[0037] Specifically, the material receiving rack 310 is provided with an alignment plate 330, and the docking component includes a material pressing plate 340 that can press the coil against the alignment plate 330. The alignment plate 330 can position the coil so as to accurately align the starting end of the standby coil to be connected (the second group of coils 292) with the end of the corresponding coil. The alignment plate 330 and the material pressing plate 340 can be provided with a positioning mechanism for positioning the coil.

[0038] In this embodiment, the alignment plate 330 is provided with a first adsorption hole 331; the pressing plate 340 is provided with a second adsorption hole 341. The first adsorption hole 331 and the second adsorption hole 341 are respectively connected to negative pressure tubes that can be independently controlled, so that the coil can be attached to the alignment plate 330 and the pressing plate 340 by negative pressure adsorption.

The cutter drive member may be a motor cam mechanism or a linear motor, etc.

[0040] Specifically, one side of the alignment plate 330 can be rotatably connected to the material receiving frame 310 through a flip structure or a lifting mechanism. Specifically, the material pressing plate 340 is provided with a pressure bar 350 for pressing the coil on the material pressing plate 340, and the pressure bar 350 is connected to a pressure clamp driving assembly, which can be a cylinder or the like.

[0041] In a specific application, during the normal operation of the coil on the first shaft 201, the coil is placed on the second shaft 202, and the pressure strip 350 is driven by the cylinder to press the coil on the pressure plate 340 of the material receiving component 300 and can be cut with a knife, and then placed on the alignment plate 330 for adsorption, and the tape is attached. One side of the tape is adhered to the coil, and the other side is on the anti-adhesive layer of the alignment plate 330. After completing the above steps, the pressure plate 340 is covered, and the second adsorption hole 341 of the pressure plate 340 is opened, and the first adsorption hole 331 on the alignment plate 330 is turned off. At this time, the coil is sucked by the adsorption surface of the pressure plate 340, and the pressure plate 340 is opened, and the alignment plate 330 is turned over to one side, and then the pressure plate 340 that absorbs the coil is covered, and the coil is waiting for docking. When the coil on the first shaft 201 is almost finished, the coil is separated from the first shaft 201, and the first cutter automatically moves to the cutting position. The lower knife moves upward to cut the material. At this time, the coil of the first shaft 201 has been cut off, and the pressing plate 340 presses down on the cut coil, and the tape just sticks to the cut coil, and the coil is successfully docked. After the above docking is completed, the first rotating drive component 230 drives the turntable 210 to rotate the coil on the second shaft 202 to the unloading position, and the other shaft is loaded with a new coil to repeat the above process, and repeat it over and over again, changing the roll and unloading the material without stopping the machine.

[0044] Specifically, the material receiving rack 310 may be provided with a glue sticking assembly for sticking adhesive tape to the starting end and / or the end of the coil. The glue sticking assembly can automatically stick and cut the adhesive tape by horizontal rolling, which is conducive to improving the degree of automation.

[0045] Specifically, the material receiving frame 310 is connected to a second flipping driving component for driving the material pressing plate 340 to flip. The second flipping driving component can automatically control the flipping of the material pressing plate 340, which is conducive to improving the degree of automation.

[0046] Specifically, the tape can be a magnetic tape, and the rack 100 is provided with a Hall sensor for detecting magnetism to count the number of dockings and analyze the usage of the coil. In subsequent production, the corresponding Hall sensor can also be set to cut the corresponding docking point when necessary to avoid the tape from flowing into the product, which has good reliability. The rack 100 can be provided with a conveyor roller 130, which is located downstream of the material receiving component 300 (the material receiving component 300 is away from the side of the dual air shaft rotating component 200). The Hall sensor can be set at the conveyor roller 130 and connected to the main control module. The rack 100 is also provided with a touch screen 140 connected to the main control module.
